METHOD or ,EoEMING AND a hA ppl ication filed JuneTS,

In application, Serial No. 96,507, filed March 22, 1926, by Stuart W.Webb and Albert Allen, there is described a method'of forming, a mark onpaper closely simulating watermark,,.while the paper is undergoing asurface finish such the well-known linen finish.v According to ithemethod thereindescribed, the n1 arkingfiseffectedby a pattern made ofthin material such as paper, out to 'thefforni of the desired markandffixed in a position to permit its impression on the paper.

In carrying out alinen finishing method,

such, for example as described in"Patent No.,1,277,'(14:, datedSeptemberfi, 1918, the

,paper is passed between a pair of t'abric belts and while interposedtherebetweenyis passed through thef nip of heavy pressure rolls one ofwhich is" softer than theother, this operation producing thedesiredfinish of thepaper. The paper pattern "for mark} ing the papersimultaneously withits finishing and cut to the form of the desiredmark, may be fixed to thesurfaceof one of the a fabric finish.

' The object of the present. invention is to pi *ovide almethodofforming and a'p )lying tion to a pattern-carrying member, such; as abelt or rolL In accordance withthe 'method of the present invention, apattern of the desired configuration is almost wholly cut or 40 severedfrom a sheet lofpaper the pattern remaining joined to the main body ofthe paper by smalljoints which zinay be, easily it ruptured ortorn'fi'om th i a b y- LA.

LF KI Y-"Y V Figure 9shows in perspective'the partially severed pattern produced therewith,

Figure 10 illustrates the manner in which a pattern isapplied to acarrying member. a Referring; first to Figure 1 of the drawings, 1represents the upper or punch member of adie forefiecting a partialseverance of a pattern from the paper. As shown best in Figure 2, thispunch member comprises a base plate 2. from which project a) series ofpattern cuttin'gelements 3; herein shown as being letters and formingthe words Systems bond, arranged parallel to each other. The letters maybe fixed to the base2 as by welding; and are regularly spaced from" oneanotherfThe edges e of theupper, surface of each letter are well definedand constitute cuttin or punchingedges. Each letter 15 slight y notchedout at the desired surface portions 02 thereof, so that the edges 0 arediscontinuous. hen the upper member 1 is forced down against paper pplaced over a corresponding female die member 4 arranged in cooperativerelation thereunder, the cutting elements 3 punch the paper into thecorresponding recesses P of the female die, except at the portions 2.Thus, the individual letters of the pattern are almost completelysevered, small joints 7' joining the letters to the main body of thepaper where the notched-out portions it did not exert a punching orcutting action. Preferably the support 6, to which the female die isfixed, 1s hollowed out under the recesses 4 in the form of a chamber 8,filled with an absorbent material, e. g., a sponge s, filled with glueor other adhesive. Thus, in punching or cutting the pattern, the cutportions are forced into the recesses 49 of the female member 4, and theunder surfaces of these portions contact with the adhes1ve-filledabsorbent material, and acquire a coating of adhesive. Preferably, thebase is provided with a channel 9, through which adhesive may beintroduced into the chamber 8.

The partially-severed pattern may be applied on its coated sideimmediately after punching, to a pattern-carrying member. As shown inFigure 5, the pattern may be applied to one of the rolls 10 of thefabricfinishing machine. After application, allowing complete setting ordrying of the adhesive to take place, the body of the paper is graspedand pulled awayfrom the fixed patv tern, this action rupturing the paperat'the joints and completing the severance of the pattern from the bodyof the paper. Thus, only the pattern remains fixed to theroll, theindividual letters of the pattern being accurately alined and regularlyspaced to correspond with the letters 3 of the die. This method ofapplication obviates cutting of individual letters, and their individualalinement and spacing on a carrying member.

If desired,the pattern may be fixed to the inner face of afabric-finishing belt, as shown in Figure 4C, or where multi-ply beltsare employed, the pattern at may be interposed between the plies 2thereof, as shown in Figure 6. The paper to be finished, interposedbetween the fabric belts, in passing between the nip of the hard andsoft rolls 10 of the finishing machine not only acquires a fabricfinish, but also the mark impressed thereon by the pattern, the markclosely simulating a watermark.

In Figure 7 is shown a modified means for effecting partial severance ofa marking pattern from paper. As shown, to a base 12 are fixed blocks13, in which arefixed spaced spurs or prongs 14, projecting upwardlytherefrom and arranged to perforate or score paper to the configurationof the desired pattern,which, as shown, consists of letters. When asheet of paper to be cut is forced down over the prongs 13, the paper isscored or perforated to the configuration. of the desired pattern.Preferably the surfaces 6 of the blocks 13 between the prongs are coatedwith adhesive prior to the scoring of the paper. In scoring the paper,the under surface of the scored portions thus becomes coated withadhesive.

The paper is scored to the confi uration of the desired pattern,as shownin igure 9, and may be applied to a pattern-carryin member, for example,one of the rollslO 0% the linen-finishing machine and-the pattern fixedthereto, and after drying completely severed from the body of the paper.

Havin thus described certain embodiments 0 this invention, it is obviousthat various changes or modifications might be made therein withoutdeparting from its spirit or scope as defined by the appended claims.

What I claim is: V

1. A method of forming and applying a paper-marking pattern to apattern-carrying member, which comprises partially severing thepatternfrom a sheet, coating one face of t e pattern with an adhesive, applyingthe pattern to the pattern-carr ing member, allowing the adhesive toset, tiereby fixing the atternto the member, and then pulling the bodyof the paper away from the member to effect a complete severance of thepattern which alone remains on the patterncarrying member.

2. A method of forming and applying a. paper-marking pattern to apattern-carrying member, which comprises partially severing a patternfrom a sheet and simultaneously coating a face of the pattern with anadhesive, applying the pattern to the patterncarrying member, allowingthe adhesive to set, thereby fixing the pattern to the member, and thenpulling the body of the paper away from the member to effect a completeseverance of the pattern which alone remains on the pattern-carryingmember.

3. A method of forming and applyinga pat-tern comprising letters, to apattern-carrying member, which com rises partially severing the lettersfrom ash eet of paper in spaced and alinedrelation, coating a face ofthe letters With an adhesive, applying the pattern to a pattern-carryingvmember, allowing the adhesive to set, thereby fixing the pattern to themember, and then pulling the ody of the paper away from the member toeffect a complete severance of the pattern which alone remains on thepattern-carrying member. r

4. A method of forming and applying a paper-marking pattern to apattern-carrya die on to an adhesive, thereby coating one face of thepartially punched pattern with an adhesive, applying thepattern to thepattern-carrying member, allowing the adhesive to set, thereby fixingthe pattern to the member, and then pulling the body of the paper awayfrom the member to efi'ect a, complete severance of the pattern which 10alone remains on the pattern carrying member. i

In testimony whereof I have afiixed my signature.
